I have 4 Sunon Hi Power 80mm on mine, the standard duel front intake and dual rear exhaust. Anyway, it's LOUD, so I have an SPST Fanbus to control the fannoice, usually I only have them on half mode (only one exhaust and one intake), that quiet it quiet a bit, but in this cold winter, I usually just run it w/ all fans turned off, your cpu shouldn't overheat.
